摘要：A motor vehicle speed control system which, upon activation by the vehicleoperator, maintains the vehicle at a predetermined set speed. The system utilizes a duty-cycle type pneumatic servoactuator responsive to an electrical control signal forcontrolling movement of the vehicle throttle. Control means responsive to deviation ofvehicle speed from the predetermined set speed, is operable to vary the control signalcharacteristics in accordance with a predetermined governing equation and the electricalcontrol signal is utilized to operate the servoactuator. Vehicle speed is sensed by agenerator providing an electrical signal output and a control means is of the electronictype responsive to the electrical speed signal and the predetermined set speed. In oneembodiment both analog-digital circuit techniques are employed for the control meansand, in another embodiment, substantially all-digital circuitry is utilized.
